Referring now to the drawings 1 to 7 by reference characters, there isshown a laundry counter generally indicated as 10'. A receptacle 12,having an opening 14 therein, for receiving pieces of cloth is shown. Aledge 16 fastened to the inside wall of the receptacle and adapted tosupport the upper edge of container or bucket 18 when pieces of clothare disposed or dumped into the A receptacle. A platform 20 .capable ofsupporting a person for disposing the pieces of cloth from upturnedbuckets ice 18 is mounted close to the receptacle 12 opposite an opening22 in the receptacle. A rotatable roller 24 mounted within the bottomportion ofthe receptacle 12 is connected by means of lan endlessconveyor belt 28 to another roller 26 positioned on the same horizontalplane as the roller 24. A rotary pronged pickup device 12a is drivenfrom roller 24 by pulley 24 to transfer clothes from opening 14 toopening 14 separated by Wall 12'. The other roller 26 is rotatablymounted on the rigid stand 30 which is positioned near the outgoing endof the housing 32. Within the receptacle 12 there is a shield 34 fixedlymounted to the inside wall of the receptacle and positioned above theupper stretch Iof the belt 28 at the roller 24. This shield ispositioned in such 4a manner that it prevents the pieces of cloth fromslipping under the roller 24. Legs 36 are provided for the receptacle 12so that rollers 24 and 26 could be maintained on the same horizontalplane with each other.

Next to the receptacle 12 there is motor means 38 which is adapted toturn the driving rollers 40, 42 and 44. These rollers are verticallyspaced from each other and are shielded from .the conveyor belt 28 by ametallic shield 46. Motor means is also connected to the belt tensioningrollers 48, 50, 52 which are vertically spaced from each other, and areadapted to provide tension to endless pick-up belts 54, 56, 58. Thesebelts extend past housing 32 and 'are also engaged by rotatable rollers66, 62, 64 which `are spaced from each other in an inclined manner.Furthermore, beneath the bottom portion Iof each belt there aretensioning rollers 66, 68, 78 which are also spa-ced from each other inan inclined manner. Thus, the endless belt S4 is adapted to be moved ina clockwise direction by the driving roller 40. This belt extendshorizontally past housing 32 and winds around the outside portion ofrotatable roller 60, which is connected to the ceiling 72 by means of asupport frame 74. The bottom portion of the endless belt 54 is engagedby rotatable tension roller 66 which is mounted in any convenientfashion to the support frame 74 and then the bottom portion of belt 54is engaged by another tensioning roller 48 rotatably mounted on themotor means 38. The endless belt 56 is adapted to be -moved in aclockwise direction by the driving roller 42, this belt extendinghorizontally past housing 32 and Winding around the outside portion ofthe rotatable roller 62, which is connected to the ceiling 72 by meansof support frame 76. The bottom portion of the endless belt 56 isengaged by rotatable tension roller 68, which is mounted in anyconvenient fashion to the support frame 76, and then the bottom portionof belt 56 is engaged by ano-ther tensioning roller 50 rotatably mountedon motor means 38, The endless belt 58 is adapted to be moved in aclockwise direction by the driving roller 44, this belt extendinghorizontally past conveyor housing 32 but terminating before roller 62and tensioning roller 68. Belt 58 winds around the outside portion ofthe rotatable roller 64, which is connected to the ceiling 72 by meansof support frame 78. 'I'he bottom portion of the endless belt 58 isengaged by rotatable tension roller 70, which is mounted in any.convenient fashion to the support frame 78, and then the bottom portionof the belt 58 is engaged by another tensioning roller 52 rotatablymounted on motor means 38. It should be noted that endless bel-ts 54,56, 58 are spaced from each other at equal distances land positioned oneIabove the other.

The conveyor housing 32 comprises cabinets 32a, 32h, 32e which areconstructed out of sheet metal. Each of the cabinets have a front sidea, 80b, 80e, a back side 82a, 8219, 82C and a top side 83a, 83b, 83e.Back and front sides are rigidly connected with each other by means ofsteel beams 84 in any desired fashion. The upper portion of the frontside of cabinet 32a shows three openings 86a,

8811, 9011 which are of rectangular configuration and are positioned oneabove the other. The upper portions of the front side of cabinet 32b and32C have identical openings 86b, 88b, 90b and 86C, 88C, 90C. Top side8311 of cabinet 32a can be opened when stud 92 of the latch arrangement94 is lifted thus releasing door 96 when it is necessary to performmaintenance duties or disengage conveyor housing 32 from the belts.Doors 96 are supported lon hinges 95 one end of which is connected tothe back sides 82a, 82b, 82C, respectively. Top side 83b and top side831' have identical arrangements for releasing their respective doors 96at the top side 8311 of the cabinet 3211. It should be noted that theupper portions of the sides of the respective cabinets 3211, 32h, 32Care open to receive endless belts 54, 56, 58 in such a manner that theopenings 86a, 86b, 86C are adapted to be used for disposal of pieces oflaundry on endless pick-up belt 54. Openings 8811, 8811, 88C are adaptedto be used for disposalv of laundry on endless pick-up belt 56 andopenings 9011, 90b, 90C are adapted to be used with endless belt 58. Inorder to facilitate easier moving or positioning of the cabinets,underneath each cabinet 3211, 32b, 32e a caster wheel arrangement 98 isprovided (see FIG. 5).

As clearly shown in FIG. 4, in cabinet 3211, light source units 10011,10011 and 10011 are mounted on the inside of the frame 8011 at side10411 thereof and one side of the openings 8611, 8811, 9011. On theopposite side of the openings and on the frame 8011, mirrors 100, 100and 100 are mounted. On the one side of the frame 8011 is a photocell10211 and a control unit 10811 for operating the counter 11011 which ismounted on the outside of frame 80a and on the opposite side of thelight source unit 10011 which is adapted to transmit from mirror 100 adirect light beam to the photocell 10211. Control unit 10811 is directlyconnected with counter 11011 by means of wire 11211 and counter 11011 isconnected with another horizontally disposed counter 11011 by means ofwire 11411 and a connector unit 11611. The light source unit 10011 ismounted on the inside of frame 8011 and positioned near one side 10411of the opening 8811. A photocell 10211 is mounted on the inside of theframe 80a near the opening 8811 to receive light from mirror 100. On theoutside of frame 8011 and on the opposite side of photocell 10211control unit 10811' is provided for operating the counter 11011 whichismounted on the outside of frame 8011 and on the opposite side of thelight source unit 10011' which is adapted to direct the light beam tothe photocell 10211.

Control unit 10811 is directly connected with counter 11011 by means ofwire 11411 and a connector unit 11611. A light source unit 10011 ismounted on the inside frame 80a and positioned near one side 104a" ofthe opening 9011. A photocell 10211 is mounted on the inside of theframe 8011 of the opening 9011 to receive light from light source 10011and mirror 100". A photocell 10261" and control unit 10811 is providedfor operating the counter 11011'l which is mounted on the outside offrame 8011 and on the opposite side of the light source unit 10011 whichis adapted to direct the light beam from mirror 100" to the photocell10211. Control unit 10811" is directly connected with counter 11011 bymeans of wire 11211l and counter 11011 is also with another horizontallydisposed t counter 110b".

It should be noted that in cabinets 3211 and 32C all the components areidentical and correspond with the components found in cabinet 3211.Thus, in cabinet 3212 the photocells are designated as 102]), 102b,102b"; the light source units are 100b, 102b, 102b; counters are 110b,110b, 110b and the like. In cabinet 32C the photocells are 102e, 102e',102c; the light source units are 100e, 100C', 100c; counters are 110C,110e', 110CH and the like.

It can be seen from FIG. 6 that all counters yare connected to maincounter 118. In the front portion 119 of the main counter is shown thatthe sum of numerical values found in counters 11011, b, '110e compriserow A. The corresponding subsequent rows of counters comprise row B androw C respectively. Total additions for each row are shown on indicators12011, 12011, C located on front portion 119 of the main counter 120.Side portion 122 of the main counter 118 features an automatic reset key124 which is adapted to eliminate all the numerical values appearing inthe indicators `12011, 12011, 1201` and reset the main counter 120 fornew operations. Each row is provided with a push button 12611, 126b,126C and slots 128a, 12819, 128C. In addition to the abovementionedslots and buttons, a slot 130 and a button 132 are provided. On the topof slot 130 an inscription is made depicting the word TOTAL As can beseen from the cutout in the main counter 118 in the back of each slotprovisions are made for rolls of tabulating paper 134. The main counteris also connected to a power source of 120e.

In operation when, for example, button 12611 is pushed a slip oftabulating paper 134 will slide out of slot 12811. On this slip of paperthe total amount of laundry pieces of row A (i.e. counted by counters11011, 110b, 110e) will be indicated. If lbutton 132 is pushed the slipof paper will depict the total amount -of laundry counted by all`counters in rows A, B and C. Main counter 118 is xedly mounted to thecontrol panel 136 which, in turn, is mounted on a stand 138 in anyacceptable manner.

Furthermore, it should be noted that pieces of cloth leaving the endlessbelt 58 drop to the basket 140; pieces of cloth leaving the endless belt56 drop to the basket 142; and pieces of cloth leaving the conveyor belt54 drop to the basket 144. Each of the baskets is connected with thewheel means 146 which are adapted to travel on rails 148. In order tolmake it certain that none of the laundry pieces will not fall on theiioor 150, guide plate 152 is provided for the basket 144 and attachedthereto in any acceptable manner. Similarly, a guide plate 154 isprovided for the basket 142 and mounted thereto in any suitable manner.

As shown in FIGS. 2 and 3 full baskets 140, 142, 144 are driven Ionrails 148 to their respective washing machines. There the baskets areunloaded into washing machine 156; baskets 142 are unloaded into washingmachine 158; and the baskets 144 are unloaded into washing machine 160.

In operation, the laundry pieces reaching conveyor belt 28 are sortedout by operators, who throw or cast the heavily soiled pieces one afteranother through openings 86a, l86b, 86C. 'Ihese pieces before landing onendless pick-up belt 54 penetrate through the light beams positionedbetween photo cells 10211, I102b, 102e and light sources 10011, 100b,1001-. The momentum of the passing laundry piece interrupts the lightbeams. The interruption of each of the light beams actuatesphotoelectric circuit, which in turn causes the electric counters 11011,110b, 110C to operate and to indicate the true number of times the lightbeams have been interrupted and thereby perform a counting function. Themedium soiled pieces 4are thrown one after another through the openings10211', 102b, 102C and interrupt the corresponding light beams in amanner identical with the previously described procedure and registeringcorresponding numerical values on the electric counters. The lightlysoiled pieces also pass through their respective light beams, arecounted and land on the endless belt 5-8 ina manner which is identicalwith the .operation described in connection with the heavily and mediumsoiled laundry pieces. For example, due to the clockwise movement of thebelt 58 the least soiled laundry pieces land in a basket A (140). Whenthe basket is filled up, the basket A is dispatched to the washingmachine 156. For sake of record keeping, the button 126e is pushed toreceive Va paper slip 134 indicating the total number of laundry piecesin the basket A. It should be noted that previously described operationscan be performed in connection with counting fof medium and heavilysoiled pieces, i.e., rows B and A, respectively. 4If the operatordesires to count all the laundry pieces found in baskets A, 'B and C andto have la record thereof the button 132 is pushed.

In the modied form of this invention, as shown in FIG. 8, the laundrypieces which land in the basket 210, from the moving endless belt 200mounted on rollers 202 (one shown), are interrupting a light beam formedby a light source 204 mounted on the wall 218 and a photocell 206mounted on the wall 220. A counter 208 connected to ythe photocell 206is adapted to count interruptions of the light beam, i.e., pieces oflaundry passing through the light beam and falling into the basket 210.When the basket is vfilled up with laundry pieces, i.e., when thepredetermined number of laundry pieces is registered by counter 208, thecart brake 214 is released causing the wheel means 212, upon which thebasket 210 is mounted, to drive the basket to its assigned was-hingmachine (not shown). The rails 216 between the washing machine and thecart -brake 214 are slightly inclined thus providing suticient drivingmomentum for the wheels 212. It should be noted that this modified formof the invention eliminates the need to watch the main counter and thenmanually dispatch the basket to the washing machine. The electric .powerfor counter 208, light source 204, photocell 206 and cart brake isprovided by the power source 220.

Materials of construction are those that are conventionally used of likeparts in other machines. Thus endless belts may be of canvas. The lightsources, photocells and canvas are simple and effective in operation andthe count is not affected by crumpled laundry pieces.

It will be understood that it is intended to cover all changes :andmodificati-ons of the example of the invention herein chosen for thepurpose of illustration which do not constitute departures from thespirit of the invention.
